TITLE: Design of sheet metal bracket.

OBJECTIVE: The objective of this project is to design a Sheet metal Bracket using Siemens NX Sheet metal workbench.

INTRODUCTION: A bracket is any intermediate component for fixing one part to another, usually larger part. Which makes a bracket is that it is intermediate between the two and fixes the one to the other. Brackets vary widely in shape, but a prototypical bracket is the L-shaped.

DESIGN METHODOLOGY:

DESCRIPTION:

SKETCH: It is the 2D representation of the model with respect to the plane or view.

CONTOUR FLANGE: Creates a base feature by extruding a sketch along a vector, or adds material by sweeping a sketch along an edge or chain of edges.

NORMAL CUTOUT: It cuts the model perpendicular to the sketch.

BRAKE CORNER: Rounds of chamfers a sharp corner of a tab or flange.

UNBEND: Flattens a bend and the material adjacent to the bend.

REBEND: Restores an unbend feature to its previous bent state, along with any features added after unbend feature.

ADVANCE FLANGE: Adds a flange along an edge using a bend angle or a reference face, the edge and reference face can be curved.

HOLE: Adds hole to one or more solid bodies in a part or assembly.

GUSSET: Gussets are used to strengthen a flange without the need for secondary processes such as welding. A general guideline suggests that the width and depth of the gusset at angle of 45degree is directly propositional to the radius and material thickness.

FLAT PATTERN: Flat pattern tool is used to automatically create a flattened version of a sheet metal part and prepare the model for manufacture. The flat pattern feature remains the last feature in model tree and maintains the flat model view.
